David Fenyes a2bf0d93a0 Fix wrong apple-II mount dimensions 
- pulled in the right border and mounting holes for Apple-II mounting dimensions
- modified the "~^" key courtyard to allow closer positioning of the upper right
  Apple II Mounting hole.  (The ~^ key is not installed in an Apple II keyboard)
- Moved tracks and diodes as needed to keep everything in the new outline.

Unified ASCII Keyboard

This project aims to provide a (near) universal ASCII keyboard for vintage computers. Home computers of the 1970's typically either polled a switch matrix, or interfaced to a parallel ASCII keyboard via a parallel port.

The keyboard allows use of Cherry MX keys, or Futaba MD-4PCS (aka eorge Risk KBM-01-01) keys.

The keyboard is designed using KiCad in order to be the most useful for anybody wishing to modify the keyboard for more specific uses, or to add to the project.

This keyboard project so far consists of:

  • A classic retro-style ASCII keyboard, modeled after the ADM-3A keyboard, which can be also be populated to fit perfectly in an Apple II/II+ case, or an OSI case.
  • A keyscan/decoder interface module that can output parallel ASCII, and can be adapted for other protocols.
  • An OSI-compatible interface module.
